LII THE SELJUK TURKS in returned alive from a quest on which they had been sent by the " Shaykh of the Mountain." Mahmud) A.H. 485 (1092) ; Barkiyaruk, A.H. 487 (1094) ; Malik Shah //., A.H. 498 (1104) ; Mohamed, A.H. 498-511 (1104-1117).—The death of Malik Shah unchained fierce rivalries. He had four sons, all of whom ultimately reigned, the latest and most illustrious being Sultan Sanjar, or cc the Hawk." Turkan Khatun was at Baghdad with Mahmud, a child of four, at the time of her husband's decease, and im- mediately brought influence to bear upon the Caliph Muktadi to secure her son's accession. In this she succeeded, and a high official was sent on posthorses to Isfahan with orders to seize Barkiyaruk, Malik Shah's eldest son by another wife, Zobayda. But this attempt was forestalled by the sons of the Nizam-ul-Mulk, and Barkiyaruk, a boy of twelve, was taken off to Rei, where he was crowned. Turkan Khatun had followed her emissary and gained possession of Isfahan, where she was soon attacked by the supporters of Barkiyaruk, who, however, were bought off. Shortly afterwards Turkan Khatun, by promise of marriage, induced Malik Ismail, brother of Zobayda, to attack the rival of her son ; but he was defeated, and Barkiyaruk was formally proclaimed at Baghdad two years after the death of Malik Shah. But this did not end the troubles ; for Tutush, a paternal uncle and the founder of the Syrian dynasty, rose in rebellion and captured the young Sultan, whom he brought to Isfahan and threw into prison. It had been decided to blind him, but his half-brother Mahmud suddenly died of smallpox, and Barkiyaruk was there- upon restored to the throne, owing partly, no doubt, to the disappearance from the scene of Turkan Khatun, who had been put to death a short time before. Barkiyaruk, who appears to have profited by his lessons in the school of adversity, defeated and killed Tutush in the following year, and another rebellious uncle was oppor- tunely removed by the hand of a page. In the course of these stirring events the life of Barkiyaruk also was at- tempted by one of the Ismaili devotees, but he escaped.
